SA8954 Special Locking Arrangements
R12092 Auxiliary Locks
GENERAL DESCRIPTION:
The electromagnet mounts rigidly to the door frame header. The armature mounts to the
door. The armature is designed to pivot about its center compensating for door misalignment. When the door is closed
the energized magnet will bond with the armature, providing auxiliary locking force. If the opening is fire rated, the
door must be secured positively with a mechanical latching device, in addition to the magnetic lock, in accordance
with local authority having jurisdiction. Locknetics manufactures fire rated mechanical latching devices. The electroni-
cally controlled 390 DEL and 390-2 DEL series magnetic locks described in this manual share the same access con-
trol circuitry. With optional access control input devices (Locknetics keypads or iButton readers) the locks can hold up
to 150 codes or iButtons standard for access, toggle, lockout, or special functions. Dry contact inputs allow for fire
alarm tie in and remote release/reset capabilities. This manual covers the mechanical installation, wiring, and manual
programming aspects of the locks. For computer programming, see information provided with the software package
you will be using.
THIS MANUAL COVERS THE 390 DEL AND 390-2 DEL, DELAYED EGRESS MAGNETS:
Delayed egress is initiated by a “plunger” switch which is actuated by a spring-loaded armature plate. By setting dip-
switches, an auxiliary switch, such as an exit device or pushbutton, can be used as well. (See dipswitch/terminal lay-
out on page 9.) The nuisance delay can be set from 0-3 seconds in the standard unit (fixed at 1 second in the BOCA
unit). The delay time is generally fixed at 15 seconds, but, with approval of the local authority having jurisdiction, can
be set to 30 seconds in the standard unit.
DESCRIPTION OF OPTIONS:
DSM:
Door Status Monitor will provide status of door with or without power applied.
MBS:
Magnetic Bond Sensor will provide status of lock (locked or unlocked) with or without power applied.
SEC:
Security Alarm will close alarm relay contacts if the door is forced open or after it is propped open for a selec-
table time period. (See page12). Anti tailgate is also in effect: the door will relock as soon as it closes, even if the
relock time delay has not yet transpired.
BOCA:
Some areas adhere to this life safety code for delayed egress. The nuisance delay is fixed at one second and
the delayed egress time at 15 seconds. After delayed egress has been initiated and the door opened, the alarm will
automatically reset after 30 seconds and the door will relock. If the door is opened within the 30 seconds the timer will
begin again.
ATR:
Audit Trail Retrieval uses computer programming and interrogation of the lock to store and retrieve the past 100
events such as access, alarm, and reset functions and the time that they occur.
